Questions
How big is the PAL-2-PSIO v0.1 PCB?
It measures 60.2 × 80.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PAL-2-PSIO v0.1 use?
27 parts, built around the MAX202ID. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PAL-2-PSIO v0.1 KiCad files?
From the venice1200/Retro repository on GitHub, at the commit this page was made from: the board is PAL-2/PAL-2-PSIO_v0.1/PAL-2-PSIO_v0.1.kicad_pcb and its schematic MSX/O1MEGA/KiCad/o1mega_THT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PAL-2-PSIO v0.1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
